It depends on a person's physical quality. People with a large base will have a better life. Duoyan Zheng's weight-loss exercises are still helpful for shaping. Thirty minutes a day, even if you are not thin, is definitely good for your health. I have an aunt who has a bad cervical vertebra and insisted on dancing Duoyan Zheng every day for a month. She feels very relaxed, and she didn't feel tired before ~
